  • Patent number: 9867340
    Abstract: A self-contained and low-maintenance two-piece planter providing significantly extended self-watering time for plants in an upper member supported by a fluid-containing lower member. An exterior indentation on the bottom perimeter edge of the upper member engages a small interior ledge positioned near the top edge of the lower member to provide a stable and readily-separable connection between upper and lower members. The upper member's bottom surface supports a fill-tube and has perforations covered by fluid-permeable material, and at least one wicking member is positioned on the material with an end extending through one of the perforations. Plants may be in pots supported by the upper member, or plants may be rooted in a growth/support medium distributed therein. No municipal power or water supply connections are used. Applications include, but are not limited to, daily self-watering of plants in residential homes, shopping malls, commercial buildings, hotels, convention centers, and college campuses.

  • Patent number: 9089861
    Abstract: A chemical dispensing apparatus includes a housing that is connectable to a source of water, such as a standard garden hose, and an internal space in which is disposed a rotatable container containing a quantity of chemical concentrate to be mixed with the source of water as it flows through the housing and is dispensed from the housing from a sprinkler head or misting nozzle. The flow of water through the housing powers a water turbine which is connected to the rotatable container, such that the container is rotated as water flows through the housing. In an alternative embodiment, the water turbine is replaced with an electric motor. Rotation of the container cause the chemical concentrate to dissolve which is then mixed with the water before it is dispensed through the sprinkler or mister.

    Abstract: A method for the evaporative production of phenol-BPA adduct crystals in a crystallizer is provided. First, a supersaturated BPA solution is introduced into a crystallizer that includes a cylindrical vessel and a concentrically-disposed draft tube that defines an annular space between the vessel and tube. Next, the BPA solution is circulated through the draft tube and annular space while a coolant is uniformly distributed in the circulating flow by radially injecting a volatile hydrocarbon compound at between about 30% and 60% of a radial extent of the annular space of to form a BPA mixture. Phenol-BPA adduct crystals are produced in the vessel by evaporating the volatile hydrocarbon compound out of the BPA mixture. The method provides a consistent and uniform concentration of coolant across the surface of the boiling zone that prevents or at least reduces unwanted crystal nucleation.

  • Patent number: 6872303
    Abstract: The water treatment cartridge is a cartridge adapted to fit into a conventional water filter housing to release a sanitizing dose of a water-treating chemical, and in particular chlorine dioxide, into a water treatment system or unit process. The cartridge is filled with a water treating media, comprised preferably of a mixture of an inert filler material and a chemical composition that releases chlorine dioxide on contact with water. The concentration of the chlorine dioxide released into the water, as well as the duration of the release, may be varied by the selection of the filler material and amount of the filler material in the water treating media.

  • Patent number: 6749807
    Abstract: A single-use cartridge C contains a dose of a concentrated decontaminant for providing a decontaminant solution upon mixing with water. The cartridge is inserted into the well (16) of a decontamination system (A). Fresh water and then the decontaminant solution are recirculated through the well during a decontamination cycle. The cartridge includes a porous region (42), through which the decontaminant solution flows. Impregnated in the porous region is a chemical indicator (44), such as crystal violet, which gradually changes color on exposure to the decontaminant. The indicator provides a semi-quantitative indication of the integrated level of the decontaminant in the solution over time for determining whether an acceptable level of the decontaminant was present for decontamination. A preferred embodiment of the cartridge C includes nested inner and outer water-penetrable cups (50,150,70,170) for holding first and second reagents. The two cups are sealed together adjacent upper open ends (56,92,156,192).

  • Patent number: 6667015
    Abstract: An apparatus for extracting biomass includes a closed loop circuit having an extraction vessel (11), an evaporator (12), a compressor (13), a condenser (14) and (optionally) a storage reservoir (15) operatively connected in series. A pumped recirculation loop (20) recirculates a portion of the output of the extraction vessel (11) for further contact with biomass. One or more modifiable resistances to flow (12;23) control the flow of solvent around the recirculation loop (20) and the main closed loop.

  • Patent number: 6565818
    Abstract: A recycling system melts unused portions of soap in order to improve the efficiency of the soaking procedure. A chamber has a pump and a screen that holds the soap disposed therein, while a tube member connects to the chamber. One or two conduits are fluid flow connected to the outlet port of the pump and each have one or more jets that protrude through the tube member. Soap is placed onto the screen and water is drawn into the chamber by the pump. The inlet pattern of the pump creates a flow of water that flows over the soap on the screen, with the soap laden water being pumped through the conduits and discharged into the sink by the jets. Now that the soap has melted into soap laden water, pieces and bits of soap will not stick to the fabric at the conclusion of the soak wash period. A fluid level switch deactivates the pump if the water within the sink falls below a certain level.

  • Patent number: 6518313
    Abstract: Solid sanitizing compositions have advantages over corresponding liquids and powders. A solid sanitizing product can be contained within a plastic bottle with a label indicating that the contents have antimicrobial or deodorizing properties containing a non-flowable solid composition having greater than about 0.02 percent by weight antimicrobial compounds. The preferred solid sanitizing compositions consist essentially of an antimicrobial compound selected from the group consisting of quaternary ammonium salts, fatty amines and diamines, chlorhexidine gluconate, phenol, derivatives of phenol, parachloro metaxylenol and mixtures thereof, and between 0 and 99.98 percent by weight of a cleaning composition. The solid sanitizing compositions can be effectively used with solid dispensers. The solid dispensers have a bowl with a drain at the bottom and an upward pointing spray nozzle.

  • Publication number: 20020033364
    Abstract: Apparatus and method for dissolving chemical tablets for creating a variable rate of chemical dissolution in a stream of constant flow rate of untreated liquid, especially water. The apparatus includes a housing in which a container is placed. The container includes a sieve plate or perforated grid which separates the container into an upper chamber in which chemical tablets are stored and a lower mixing chamber. A collection reservoir is defined in an annular outside the container wall and inside of the housing. Several arrangements are illustrated by which a vortex of liquid is generated of controllable variable intensity in the lower or mixing chamber thereby creating uneven liquid pressure beneath the perforated grid as a function of radial distance. As a result, fluid passes aggressively through outer radial perforations or holes in the grid and which impinge on the chemical tablets stacked on the grid.
